Graphene has long been touted as the miracle material, with scientists promising us all the wondrous things it could help us accomplish. One of those things is better batteries, and a new process could help that happen.
Scientists in South Korea have created a highly conductive, stable electrode by spraying droplets of graphene into a hot blend of acid and organic solvent, a process that’s being referred to as ‘deep-frying’ the graphene.
The ‘pom-poms’ created by this process aren’t as tasty as a bag of chips, but they do come with an open 3D structure that makes them a lot better at transferring electrical charges than regular graphene. This wouldn’t be the first time science has managed to create 3D graphene, but this method is a lot more suited to mass production because of it’s simplicity and the ease in which it can done in large batches.
It’s going to be a while before we see graphene batteries hitting our gadgets, but the good news is that progress is being made so it’s going to happen someday.
